Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1008864, here are decompositions:

  • 5 + 1008859 = 1008864
  • 7 + 1008857 = 1008864
  • 11 + 1008853 = 1008864
  • 13 + 1008851 = 1008864
  • 47 + 1008817 = 1008864
  • 71 + 1008793 = 1008864
  • 83 + 1008781 = 1008864
  • 163 + 1008701 = 1008864

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 1,008,864 and was likely granted around 1911.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
